DETAILED DESCRIPTION

In the following Detailed Description, reference is made to theaccompanying drawings, which form a part hereof, and in which is shownby way of illustration specific embodiments in which the invention maybe practiced. In this regard, directional terminology, such as “top,”“bottom,” “front,” “back,” “leading,” “trailing,” etc., is used withreference to the orientation of the Figure(s) being described. Becausecomponents of embodiments can be positioned in a number of differentorientations, the directional terminology is used for purposes ofillustration and is in no way limiting. It is to be understood thatother embodiments may be utilized and structural or logical changes maybe made without departing from the scope of the present invention. Thefollowing detailed description, therefore, is not to be taken in alimiting sense, and the scope of the present invention is defined by theappended claims.

It is to be understood that the features of the various exemplaryembodiments described herein may be combined with each other, unlessspecifically noted otherwise.

In one embodiment, a component is provided. The component includes anintegrated circuit, a package body, and a first contact device, thecontact device penetrating the package body.

In another embodiment, a method for producing a device is provided. Themethod includes arranging contact devices on the carrier, arranging anintegrated component on the carrier, and introducing a material into theintermediate spaces between the contact devices and the circuit.

One embodiment provides a device with a compression-molded package body,which is arranged on a device stack or a printed circuit board. In oneembodiment, the stacking of semiconductor devices or components is asuitable measure for increasing the packing density of semiconductorcomponents by utilizing the third dimension. There is the stacking ofsemiconductor dice or chips (die stacking) and the stacking of devicesor packaged components (package stacking).

When stacking semiconductor dice, previously exposed, i.e. unpackaged,semiconductor dice or chips are stacked in a single package body. Thishas the advantage that the stack has a small height and small lateraldimensions. Furthermore, the stack can be produced at low cost. However,the semiconductor die used must be one which has already been found tobe defect-free, i.e. a “known good die” (KGD), in order to solve aproblem with the yield in semiconductor die stacking However, it is notpossible, or only with considerable effort, to test an exposedsemiconductor die in the same way as a semiconductor die alreadyprovided with a package.

When stacking devices or packaged components, semiconductor componentsare first provided with a package and then tested. After that, thesedevices are then stacked one on top of the other to form a device stack.For this purpose, a connection in the vertical direction is required inthe device stack.

The integrated component may, for example, include a semiconductorsubstrate, in particular a silicon substrate or a compound semiconductorsubstrate. However, SOI (silicon on insulator) substrates may also beused. The integrated component may include a multiplicity of electronicsemiconductor components, for example, bipolar transistors or CMOS(complementary metal oxide semiconductor) transistors.

The package body may, for example, consist of or contain an electricallyinsulating material or else, given appropriate electrical insulationwith respect to the contact devices, an electrically conductivematerial. Polymers, such as resins or plastic materials, can be used,for example, as a package body. The package body holds the constituentparts of the device together and protects the chip from environmentalinfluences, such as moisture or mechanical stress. The package body canbe produced, for example, by compression molding, printing, spin-coatingor pouring and possibly subsequent curing.

In the case of one embodiment, the contact devices may consistcompletely of a metal or a metal alloy or have a metallic surface.Suitable metals are, for example, copper, copper alloys with more than80 atomic percent of copper or solder materials. Solder balls may beused, for example, as contact devices. For example, lead-free soldersare used, but also other solders.

The penetration of the package body may be understood, or is understood,as meaning that the contact element penetrates right through the packagebody from one surface region to another surface region. The penetrationof the package body may mean, or does mean, that the contact element isenclosed or encapsulated by the package body, except for two ends of thecontact element.

For example, the contact devices are completely filled bodies, inparticular of a homogeneous material. The contact devices have a hollowcore or a core of a different material than a metallic shell of thecontact devices. For example, the core is likewise electricallyconductive or electrically insulating.

For example, conducting structures included in a wiring arrangement mayconnect the integrated circuit to the contact devices. The conductingstructures may, for example, be conducting tracks or plated-throughholes or vias.

In one embodiment of a device, the integrated circuit and the fillingmaterial as well as the contact devices may lie in a first plane. Thechip, the filling material and the contact devices are on the same sideof the wiring arrangement. This measure already allows the overallheight of a packaged component to be reduced considerably. In oneembodiment, in the case of a compact construction, the wiringarrangement extends along its width in a second plane, which liesparallel or substantially parallel to the first plane.

The contact devices may advantageously be balls. The ball form is usedbecause spherical contact devices can be produced in a simple manner,for example by solidifying metal drops. The molten metal thereby assumesthe ball form of its own accord, to minimize the surface tension. Theuse of balls also offers the advantage that, when soldering the contactdevices, the contact devices can be securely held in the package body.Should the contact devices become soft, for example during soldering,they will not change their shape again on account of the surfacetension, so that no intermediate spaces occur between the contactdevices and the package body.

The balls may in each case have a deformed side. For example, in eachcase a piece of the balls has first been removed in a planarizingprocess and then solder material has been re-applied to these locations.In another embodiment, deformed locations may also be present on twosides of the balls that are facing away from each other.

In one embodiment, the contact devices may consist completely or to 100percent of solder material, i.e. of a material with a meltingtemperature lower than 400° C. (degrees Celsius). The contact devicesmay contain solder material, for example to at least 75 atomic percent.Smaller proportions than 75 atomic percent of solder material aresufficient, for example if a coating of a solid core with soldermaterial is chosen. The use of solder material ensures goodsolderability in the mounting of the package device.

Furthermore, solder balls offer the advantage that they retain theirball form when heated, because this is a low-energy state. For example,cylindrical contact devices of solder material have a greater tendencywhen heated for a solder ball to form at an end of a cylindrical bore oropening. In this embodiment, however, solder would be sucked out fromthe bore or opening, so that solder-free locations may also occur, andthese would lead to incorrect contacting.

The contact devices may have in each case a curved line of intersectionwith a plane that extends in the direction normal to the first plane.This requirement is also met, for example, by contact devices of anellipsoid form, barrel form etc. The aforementioned technical effectsconsequently continue to apply, albeit to a reduced extent.

In one embodiment, the contact devices may be adjacent the fillingmaterial or the package body, or the first component or the circuit andthe contact devices are enclosed by the package body. This is theconsequence of a production method explained below for producing apackaged component which includes the package body, the integratedcomponent and the contact devices. In one embodiment, the package bodyis homogeneous, in particular with regard to its composition.

The package body may consist of a resin, or it contains a resin. In oneembodiment, epoxy resins are particularly well suited forcompression-molding processes, with which devices for high requirementscan be produced in a simple and low-cost manner.

The wiring arrangement may have a layer thickness of less than 15micrometers or even of less than 10 micrometers. Consequently, thewiring arrangement is not a printed circuit board which contains, forexample, FR4 (flame retardant type 4) or FR5 or BT material(bismaleimide triazine). This is because such printed circuit boardshave thicknesses of greater than 150 micrometers, even if they onlyinclude one or two layers. The wiring arrangement with the smallthickness of less than 50 micrometers is, in particular, a wiringarrangement produced by the thin-film technique, which is preferablyproduced directly on the circuit or on the package body. Consequently,there are no bonding processes or flip-chip processes at this point, andvery high-quality connections can be produced between the circuit andthe contact devices. Furthermore, the thin-film technique isparticularly suitable for producing the packaged components at waferlevel, i.e. a number of devices are processed in a slice that has theouter dimensions of a semiconductor wafer.

Also used, however, are wiring arrangements not produced by thethin-film technique on the package body, in particular wiring devices ofthe materials mentioned, such as FR4, FR5, BT or else of ceramic, etc.The wiring arrangement may, for example, also be formed from bondingwires or in some other manner.

In one embodiment, at least one lateral dimension, i.e. the width and/orthe length, of the packaged component may be less than 30 mm(millimeters) or less than 20 mm. Typical packages even have dimensionsof less than 7 mm. The height of the packaged component is also verysmall, for example less than 1 mm. For example, the package is only lessthan 10 percent higher than the contact devices. The package body hasthe same height as the integrated component. On one embodiment, devicesof small dimensions are inserted in small, portable devices, such as forexample cellphones, with a largest dimension of less than 10 cm(centimeters).

The package device also includes a second packaged component or evenmore than two packaged components. The second packaged component haspreferably been produced by the same method as the first packagedcomponent or as the first device. The two packaged components preferablylie parallel to each other, deviations occurring within the limits ofmounting tolerances, which however are smaller than, for example, 3°(angular degrees). In one embodiment, the device stack is alsoparticularly flat, in particular in comparison with a device stack withdevices in which contact devices and chips are respectively arranged onsides of the wiring arrangement that are facing away from each other.

The contact devices of the one package may preferably be soldered, forexample, onto conducting structures of the wiring arrangement of theother package. Consequently, the two components can be connected in asimple manner to form a component stack, in particular by flip-chipprocesses.

Furthermore, an embodiment of a method for producing a component isprovided, performing the processes of:

providing a carrier,

arranging a multiplicity of contact devices on the carrier,

after arranging the contact devices or before arranging the contactdevices, arranging an integrated circuit on the carrier, and

after arranging the circuit and the contact devices, introducing amaterial into the intermediate spaces between the contact devices orbetween the contact devices and the circuit. The material is preferablyelectrically insulating.

The method serves in particular for producing an aforementioned circuitarrangement, so that the technical effects mentioned there also apply tothe method.

The contact devices may be arranged on the carrier in the solid state.Solid means here that the contact devices are not applied as a paste,i.e. in a pasty state.

Solder balls may preferably be arranged as contact devices. Used, forexample, in this case is a commercially available machine that is alsoused for the placing of solder balls on intermediate printed circuitboards, for example in the production of what is known as a BGA (ballgrid array). The solder balls are sucked by the machine, for examplewith the aid of a negative pressure or a vacuum, onto a holding device,which contains bores at the locations at which solder balls are to bearranged. The holding device is then set down on the carrier, where thesolder balls are released from the holding device, for example byswitching off the negative pressure. This procedure is likewise suitablefor processes that are carried out at wafer level, i.e. here a waferformed by the filling material or package bodies. In this case, forexample, over 1000 solder balls are placed simultaneously.

In one embodiment, a filling material for the package body may beintroduced by a compression-molding process. These compression-moldingprocesses are likewise suitable for the production of wafers from thefilling material or package bodies. Consequently, after thecompression-molding, the filling material has dimensions like asemiconductor wafer, for example a diameter of 20 cm (centimeters), 30cm or more than 30 cm. Consequently, machines that are otherwise used orcould be used for the processing of semiconductor wafers are used or canbe used in particular for producing the wiring arrangement.

The filling material or the package body is or may preferably be workedback, so that the contact devices are exposed on the worked-back side ofthe filling material or package body. For example, an etching-backprocess or a chemical-mechanical polishing process is used. Justmechanical polishing processes may also be suitable. The working-backprocess produces a planar surface, which facilitates later mounting.Furthermore, the planar surface is particularly suitable for carryingout further method processes, for example, as part of a thin-filmtechnique or screen printing to apply a solder paste to the contactdevices.

In one embodiment, a wiring arrangement may be produced by the thin-filmtechnique on the circuit or on the contact devices and on the packagebody. Consequently, layer depositing processes and lithography processessuch as are used in the case of integrated circuits are used, althoughin the case of the thin-film technique the minimum dimensions aretypically greater than or equal to the minimum dimensions in the uppermetallization layer of an integrated circuit. A very flat packagedcomponent is obtained, in particular requiring no printed circuit board.The thin-film technique is also suitable for processing at wafer level,i.e. here a number of packaged components can be produced from or in afilling-material wafer.

The contact devices may also be provided with a solder material, forexample, with solder paste, on the side that is facing away from thewiring arrangement. The solder paste is applied, for example, by usingscreen printing. The thermal loading is particularly low when solderpaste is used in this method.

In particular, the packaged component or the device may be soldered ontoa further device after singulating or before singulating, the furtherdevice likewise including an integrated component. This produces adevice stack of a small overall height.

The stated method processes may be carried out simultaneously in jointoperations for a number of devices, in particular at wafer level.Consequently, the devices can be produced in a very low-cost way.

Furthermore, protection is afforded to the use of a ball placing machinefor carrying out one of the stated processes, in particular a machinewhich places more than 1000 balls simultaneously.

To sum up, the proposed solutions mean that an intermediate carrierboard (interposer) and wire bond connections can, but do not have to be,substituted by thin-film rerouting. Furthermore, the conductive fillingfor the instances of contacting in the z direction can be carried out atthe same time as the production of the packaged component. Inparticular, known, commercially available and inexpensive materials areused, for example preformed solder balls or compression-moldingcompounds that are available on the market.

The production is also possible at wafer level, which ensures a highdegree of parallelism, and consequently low costs. The lateraldimensions of the packaged component can likewise be kept adequatelysmall on account of high-precision placement processes. A very smallpackage height is also obtained on account of the embedding of thecontact devices in the filling material. In addition, matching of thecoefficient of thermal expansion (CTE) allows, for example, solder ballsof a small diameter to be used in the case of comparatively largedimensions of the packaged component, of, for example, greater than 7millimeters in width, and the thermomechanical reliability isnevertheless great. In particular, the diameter lies below 500micrometers, below 400 micrometers or even below 200 micrometers.However, the diameter is greater than, for example, 100 micrometers.

In one embodiment, a universal package wafer compression-molding conceptis provided, with solder balls also being embedded in a molding compoundin addition to chips. This allows low-cost, flexible and very simplecontacting in the z direction to be achieved. In one embodiment, apackage-on-package stack can be constructed in a simple manner. Thematching of the coefficients of thermal expansion of the materials used,for example the coefficient of thermal expansion of the molding compoundis equal to the coefficient of thermal expansion of a printed circuitboard onto which the packaged component is soldered, allows solder ballsof a comparatively small diameter to be used, so that a particularlyflat PoP (package on package) can be produced.

Whenever “can” or “may” is mentioned in this application, both thepossibility and the actual realization of the stated measure in anembodiment are meant. Several embodiments of the invention are presentedbelow on the basis of figures, which serve merely for purposes ofillustration and are not intended to restrict the scope of theinvention.

FIG. 1 illustrates a device stack 10, which includes two devices 12 and14. The device 14 has been soldered onto the device 12, as explained inmore detail below. As an alternative to solder, a conductive adhesivemay be used for example. The device 12 has also been soldered or mountedin some other way on a printed circuit board 16, which also carriesfurther electronic components, for example resistors, capacitors orcoils, or further integrated circuits.

In the case of an alternative exemplary embodiment, the device stack 10also includes a third device 20, see line 18. The third device 20 hasthen been soldered or mounted in some other way on the device 14.

The device 12 includes an integrated component 22 or an integratedcircuit 22, for example based on a silicon substrate, in particular onan already ground-thin silicon substrate. The integrated component 22includes a multiplicity of active semiconductor components, see, forexample, transistor 23. In the exemplary embodiment, the active side ofthe component 22 is arranged toward a wiring arrangement 30. However,this is not necessarily so. The integrated component 22 also includes atleast one or more metallization layers, which however are notrepresented and lie between the active components and a wiringarrangement 30 explained in more detail further below.

Furthermore, the device 12 also includes solder balls 26 and 27, whichlie in the cross section of the device 12 that is represented in FIG. 1,and further solder balls that are not represented. All the solder balls26 and 27 are arranged in a package body 24 or enclosed by a fillingmaterial of the package body 24. The production of the device 12 isexplained in more detail below on the basis of FIGS. 2A to 2J.

The device 12 has been soldered onto the printed circuit board 16 bysoldered connections 28, 29. The soldered connections 28 and 29 havebeen produced, for example, from a solder paste. Arranged on the side ofthe device 12 that is facing away from the printed circuit board 16 is awiring arrangement 30, which in the example is produced by the thin-filmtechnique. The wiring arrangement 30 includes, for example, anelectrically insulating layer 32, for example a silicon dioxide layer,and a multiplicity of conducting tracks, of which two conducting tracks34 and 36 are represented in FIG. 1. The wiring arrangement 30 alsoincludes an optional solder resist layer 38 with openings 40, 42 forsoldered connections toward the device 14.

In the exemplary embodiment, the device 14 is constructed in a waysimilar to the device 12, in particular solder balls 126 and 127 and anintegrated component 122 are arranged in a package body 124. However,the component 122 has, for example, different functions than thecomponent 22. The functions of the components 22 and 122 are the same,for example a memory function. A transistor 123 of the component 122 isrepresented in FIG. 1, in particular in order to identify the activeside of the component 122. A wiring arrangement 130 includes conductingstructures, which are arranged differently than the conductingstructures in the wiring arrangement 30. However, wiring arrangements30, 130 with the conducting structures following the same path are alsoused in a device stack.

In the case of the exemplary embodiment, the device 20 also has aconstruction similar to that of the devices 12 and 14. In oneembodiment, there is an integrated component 222, a package body 224,solder balls 226, 227 and a wiring arrangement 230.

FIGS. 2A to 2J illustrate production stages in the production of thedevice 12 together with further devices 12 a to 12 b, see FIG. 2J. Inone embodiment, the method processes are carried out at what is known aswafer level. However, the method processes may also be carried outseparately for individual packages.

As represented in FIG. 2A, first a carrier sheet 300 is provided. Thecarrier sheet 300 consists, for example, of a metal, of silicone, of apolymer or of a ceramic or of some other material. An adhesive material,for example a double-sided adhesive film 302, is applied to the carriersheet 300.

As represented in FIG. 2B, solder balls 26, 27, 26 a, 27 a, 26 b, 27 band further solder balls that are not represented are subsequentlyplaced on the exposed side of the film 302. This placement is carriedout with the aid of a machine which automatically places the solderballs in one operation, for example, a Shibuya SBM. Alternatively, thesolder balls for a single device are simultaneously placed, after whichthe solder balls for a neighboring component are then placed on thecarrier sheet 300, and so on.

As represented in FIG. 2C, a multiplicity of integrated circuits orsemiconductor dice 22, 22 a, 22 b, etc. are placed on the film 302, forexample, with the aid of what is known as picking and placing. In thiscase, frontend-tested circuits are used in particular.

In the case of another configuration, the sequence of the methodprocesses is changed over, so that the circuits 22, 22 a, 22 b areplaced first and then the solder balls 26, 27, etc.

As represented in FIG. 2D, a compression-molding process is subsequentlycarried out, involving pressing a punch against the carrier sheet 300and forcing a compression-molding compound for a package body 324 intothe intermediate spaces between the solder balls 26, 27 and the circuit22. Subsequently, for example, the pressing device is heated in theregion of the filling material 324 until the latter has cured. Thefilling material may also be cured without additional heating. Epoxyresin filled with a filler to ensure a predetermined coefficient ofthermal expansion is used, for example, as the compression-moldingcompound. The value of the coefficient of thermal expansion is matched,for example, to the value of the coefficient of thermal expansion of theprinted circuit board 16, in particular is equal to the value of thiscoefficient of expansion.

As illustrated in FIG. 2E, after the curing of the package body 324, aworking-back process is performed, for example, by grinding materialaway, until the solder balls 26, 27, etc. are exposed on one side. Atthe point in time at which the removal is stopped, the package body 324in the exemplary embodiment still easily covers the circuits 22, 22 a,etc. In the case of other exemplary embodiments, however, as illustratedin FIG. 4, the semiconductor substrates of the components 22, 22 a,etc., for example, are also exposed, possibly even further thinned.

FIG. 2F illustrates the thinned package bodies 324 a, although thefilling-material wafer has been turned over in comparison with FIG. 2E,so that now the active side of the components 22, etc. is facing up.Furthermore, the carrier 300 and the film 302 have been removed, forexample, by using a chemical solvent or by using ultraviolet radiation.The filling-material wafer represented in FIG. 2F has the dimensions ofa semiconductor wafer, but, for example, a smaller height than asemiconductor wafer. However, the height of the filling-material wafermay also be equal to the height of a semiconductor wafer or greater.

As represented in FIG. 2G, after the production of wiring arrangements,for example the wiring arrangement 30, an insulating layer 332 isapplied. After that, the conducting structures 34, 36, 34 a, 36 a, 34 b,36 b are produced, for example, from copper, in particular with the aidof a galvanic process. In the case of another exemplary embodiment, theconducting structures are applied directly, i.e. without an insulatinglayer 332 lying in between, to the components 22 and to the package body324 a.

As represented in FIG. 2H, after the production of single-layer ormulti-layer wiring structure arrangements 30, etc., an optional solderresist layer 328 is also applied. Openings 340, 342, 340 a, 342 a, 340b, 342 b, etc., at which soldered connections to a further packagedcomponent or to an unpackaged integrated component or circuit can beestablished, are made in the solder resist layer 328.

As represented in FIG. 2I, the filling-material wafer represented inFIG. 2H is turned over once again, so that the active side of thecomponents 22, etc. is facing down again.

For example, solder paste projections 328, 329, etc. are applied withthe aid of a screen-printing process at the locations at which thecontact devices 26, 27, etc. are exposed.

As represented in FIG. 2J, the solder paste projections 328, 329 areliquefied in a thermal step, at, for example, 260° C., so as to formhemispherical solder regions 428, 429, 428 a, 429 a, 428 b, 429 b, etc.,which lie directly against the solder balls 26, 27, etc. The solderregions 428, 429, 428 a, 429 a, 428 b, 429 b preferably have a smallerdiameter or a smaller volume than the solder balls 26, 27; inparticular, the volume is less than 20 percent.

Subsequently, the devices 12, 12 a, 12 b, etc. are separated from oneanother at separating lines 450, 452. This is followed by mounting, thecomponent 12, for example, being introduced into the device stack 10.Subsequently, the device stack 10 is soldered on the printed circuitboard 16. In this soldering operation, the soldered connections 28, 29,etc. are produced from the solder regions 428, 429, etc., see FIG. 1. Itis also possible for the devices only to be separated from one anotherand attached on the printed circuit board after the stack.

In other exemplary embodiments, at first only one device of the devicestack is mounted on the printed circuit board 16. Only after that is afurther device, or are further devices, soldered or mounted on thefirst-mounted device.

In other exemplary embodiments, underfillings are used, for example,between the device 12 and the printed circuit board 16 or else betweenthe devices 12 and 14.

In one or more embodiments, there are a number of layers of conductingtracks in the wiring arrangements 30, 130, etc. It is also notimperative that in each case a solder ball 26 and a solder ball 126 arearranged one above the other. Devices with solder balls that are offsetin relation to one another can also be connected to one another by usingthe wiring arrangements lying in between.

In another exemplary embodiment, the component 12 is individuallysoldered onto the printed circuit board 16, without further components14, etc. being soldered on or mounted later. In this case, the wiringarrangement 30 preferably does not include a solder resist layer and/orany openings in the solder resist layer.

In another exemplary embodiment, different dimensions are used, inparticular the devices 12, 14, etc. may have dimensions that aredifferent from one another. Furthermore, in the case of other exemplaryembodiments, a different arrangement of contact devices is chosen, forexample, more than one row is arranged around the circuit, for exampletwo rows, three rows or more than three rows, but preferably, forexample, fewer than twenty rows.

In a further exemplary embodiment, integrated components with functionsthat are different from one another are arranged in a package body 324,324 a, and then the method processes explained on the basis of FIGS. 2Ato 2J are carried out for these components.

It is also possible for a number of integrated components to be arrangednext to one another for each device.

FIG. 3 illustrates a device 500 according to a further exemplaryembodiment. A transistor 501 is contained in an integrated component502, and is intended to illustrate the active side of the integratedcomponent 502. The device 200 also includes an optional contactarrangement 504 with respect to a wiring arrangement 506. The contactarrangement 504 includes, for example, soldered connections.

The wiring arrangement 506 is, for example,

a thin-film wiring arrangement,

a printed circuit board, for example plastic-based or ceramic-based,

another wiring arrangement, for example initially self-supporting, see,for example, bonding wires 514, 516 of, for example, Au, Al or Cu.

The device also includes a package body 508, for example epoxy-based.Arranged in the package body 508, to the side of the component 502, arecontact devices, which penetrate the package body, for example:

contact cylinders 510, for example of copper, copper alloy, aluminum oran aluminum alloy.

The contact cylinders 510, the package body 508 includes contact bodies512, which are likewise arranged to the side of the component 502 andpenetrate the package body 508. The contact body 512 has, for example, abarrel form or an ellipsoid form. In one embodiment, the contactcylinder 510 or the contact body 513 may protrude somewhat from thepackage body 508 toward the wiring arrangement 506 or terminate with thepackage body 508. Otherwise, for example, the production processesexplained above are carried out to produce the device 500.

If a self-supporting wiring device 506 is used, the bonding wires 514,516, for example, are only attached after the package body 508 isproduced.
